Word choice and formality questions ask you to match the passage's tone—usually formal, precise academic prose—and reject slang, casual phrasing, or vocabulary that is too elevated or too colloquial for context. The right word fits both meaning and register.
What the ACT rewards
Standard written English: clear, neutral-to-formal, no chatty asides. Rhetorical questions in ACT English question typesoften contrast a casual original with a polished replacement.
Common wrong answers
- Slang or texting tone in a research-style passage
- Overly ornate words when a simple precise word works
- Emotional or vague verbs where a specific verb fits
- Changes that alter meaning, not just tone
How to choose
- Read two sentences before and after the underline.
- Note the passage voice (science report vs personal essay).
- Eliminate tone mismatches first, then pick the most precise remaining choice.
